Hi Folks !

I'm quite new to develop webApps with Jboss3.0/Tomcat and every time I try to do the following code in a serverLet the server Throws me a security exception.

Does AnyOne here could give some tips to solve this issue ?

The Code :
========
Context ctx = new InitialContext() //Toncat and Jboss are running at the same jvm

The Error Message :
===============
ERROR [Engine] StandardWrapperValve[login]: Servlet.service() for servlet login threw exception
